Objectives
Present your ear defenders design, and explain your findings.
Science Objectives
i) Identify how sounds are made, associating some of them with something vibrating.
ii) Recognise that vibrations from sounds travel through a medium to the ear.
iii) Find patterns between the pitch of a sound and features of the object that produced it.
iv) Find patterns between the volume of a sound and the strength of the vibrations that produced it.
v) Recognise that sounds get fainter as the distance from the sound source increases.
Working Scientifically
- Use straightforward scientific evidence to answer questions or to support findings.
- Gather, record, classify and present data in a variety of ways to help answer questions.
Other Curriculum Areas
English
- Discuss what they are learning and to develop their wider skills in spoken language.
- Use language in a greater variety of situations, for a variety of audiences and purposes, including through drama, formal presentations and debate.
Design and Technology
- Generate, develop, model and communicate their ideas through discussion, annotated sketches, cross-sectional and exploded diagrams, prototypes, pattern pieces and computer-aided design.
- Evaluate their ideas and products against their own design criteria and consider the views of others to improve their work.
Extended Writing Opportunities
Persuasive writing: Write an advertising leaflet with diagrams describing why your ear defender design is the best.
